Adobe is fixing its products for at least 13 different security vulnerabilities, while Microsoft's tally comes in at 15. In addition to the security patches, both vendors also issued updates on their positions relative to the current threat of fraudulent SSL certificates from Certificate Authority DigiNotar.

"Microsoft Patch Tuesday would be quiet and normal, but Microsoft released an update (KB 2616676) continuing the saga of recent stolen DigiNotar certificates," Wolfgang Kandek, CTO of Qualys wrote in a blog post. "The update revokes certificates signed by two Certificate Authorities (CAs): Entrust and Cybertrust who issued certificates on behalf of DigiNotar."
